memory-device: complete factoring out pre_plug handling
With all required memory device class functions in place, we can factor out pre_plug handling of memory devices. Take proper care of errors. We still have to carry along legacy_align required for pc compatibility handling. We will factor out tracing of the address separately in a follow-up patch.
